Title: Digitally controlled oscillator
Inventor: MORISHIMA MORIHITO
IPC: H03K3/02
Filed: 1990-07-06
Abstract: PURPOSE:To correct accumulated errors by outputting a pulse each time counting high-order M bits, integrating low-order N bits, and outputting a pulse after delaying it by one cycle of a clock pulse when the integrated bits reach a carry amount. CONSTITUTION:An input register 14 holds a set data Ds(M+N) composed of the fixed number of high-order M bits and the variable number of low-order N bits. Each time a count value to be outputted from a counter 6 is M, a comparator 5 outputs a coincidence signal EQ, outputs an output pulse P0 from a selector 13 and resets the counter 6. The remaining N bits are inputted to full adders 10. For each signal EQ, a register 11 fetches the data of the full adders 10, returns the data to the full adders 10 and cumulatively adds them. When the added value reaches a carry amount M, a carry signal Co is inputted to the selector 13, and the output pulse P0 is outputted by the coincidence signal EQ delayed for one cycle of the clock pulse by a delay circuit 12. Thus, the accumulated error caused by the low-order bits is easily corrected, and accuracy is improved.

Filed: 1993-07-20
Abstract: PURPOSE:To exactly judge the logic of a received signal by supplying a threshold voltage for deciding the logic of the signal from a power supply part to be used by transmission and reception circuits at the other terminal of a transmission line. CONSTITUTION:A transmission line L is composed of (n) lines of transmission lines L1-Ln and at both the terminals of the respective transmission lines L1-Ln, transmission/reception circuits TRA1-TRAn and TRB1-TRBn composed of drivers D and receivers R are connected while being faced each other.
